Rajaraman Ramachandran - PeerSpot reviewer
Co Founder And CTO at Gamucopia Creatives
Has enabled us to manage compute resources efficiently while supporting multiple languages
AWS Lambda needs to improve cold start time. Some AWS Lambda functions require a cold start, and if you need AWS Lambda to provide quick responses, you need some of the AWS Lambdas to be always on, which is risky. We need AWS Lambda's cold start time to be reduced so that we can use it much faster than now. We need a better way to handle the cold start. We should be able to start AWS Lambda much before in a predictable way instead of just calling and then having it start.
